FAQs
How do I know it’s time to replace my HVAC unit instead of repairing it?
Most systems in Harriman last 12–15 years. If your unit is in that age range and you’re facing major repairs such as a compressor or heat-exchanger failure, replacement is usually more economical. Other tell-tale signs include rising energy bills, uneven room temperatures, frequent refrigerant top-offs (especially if the system uses phased-out R-22), and excessive noise or short-cycling. A new, high-efficiency system can cut heating and cooling costs 20–40 %, so the long-term savings often outweigh the price of continual repairs.
What size and type of HVAC system is best for homes in Harriman?
East Tennessee’s humid summers and cool winters call for a properly sized heat pump or dual-fuel system. We perform a Manual J load calculation to consider square footage, insulation, sun exposure, and window quality; rule-of-thumb sizing (1 ton per 500–600 sq ft) is never precise enough. For most homes, a 2–4-ton variable-speed heat pump rated 15 SEER2 or higher delivers the right balance of comfort and efficiency. In homes with existing gas service, a dual-fuel (heat pump + gas furnace) setup can switch to gas during freezing snaps to keep utility costs low.
How long does HVAC replacement take and what happens on installation day?
A straightforward change-out typically takes 4–8 hours. Our crew arrives at the scheduled time, lays down floor protection, and shuts off power and refrigerant. We recover the old refrigerant, remove the indoor coil and outdoor condenser, and inspect the ductwork and line set. Next, we set the new condenser on a leveled pad, install a matched indoor coil or air handler, run new thermostat and drain lines if needed, and connect electrical and refrigerant lines. After pressure testing and evacuation, we charge the system to factory specs, perform a full start-up checklist, and show you how to program the thermostat. Roane County requires a permit and a follow-up inspection, which we schedule for you.
Are there rebates, tax credits, or financing options for HVAC replacement in Harriman?
Yes. High-efficiency heat pumps (≥15.2 SEER2/≥8.1 HSPF2) qualify for a federal 25C tax credit of 30 % of the installed cost, up to $2,000. Through TVA’s EnergyRight program, Harriman Utility Board customers can earn $150–$850 back on qualifying heat pumps or dual-fuel systems. We’re a TVA Quality Contractor Network member, so we handle the paperwork. Our company also offers 0 % APR financing for up to 60 months or low-payment plans with approved credit, making it easier to upgrade without large upfront costs.
What does it cost to replace an HVAC unit in Harriman and what affects the price?
A standard 2–5-ton split heat-pump system generally runs $6,500–$12,000 installed. Ultra-high-efficiency variable-speed models, zoning controls, or dual-fuel furnaces range from $10,000–$16,000. Key cost drivers include system size, efficiency rating, brand, ductwork modifications, refrigerant line replacement, electrical upgrades, condensate management, and permit fees. We provide a detailed, no-surprise quote after a free in-home assessment.
How do I keep my new HVAC system running efficiently after replacement?
Replace or wash filters every 1–3 months, keep at least 2 ft of clearance around the outdoor unit, and rinse the condenser coil gently each spring. Schedule professional maintenance twice a year—once before cooling season and once before heating season—to check refrigerant charge, test safety controls, and clean internal components. Register your equipment within 60 days to secure the 10-year parts warranty, and consider an extended labor warranty for added peace of mind. Using a programmable or smart thermostat to limit drastic set-point changes and setting ceiling fans to the correct direction also prolongs system life and saves energy.
